This application is a continuation of U.S. Non-provisional patent application having Ser. No. 16/217,298, filed on Dec. 12, 2018, which claims the benefit of U.S. provisional patent application having Ser. No. 62/741,170, filed on Oct. 4, 2018, the contents of which are incorporated by reference herein in their entirety.

TECHNICAL FIELD

The present disclosure relates generally to wireless networks, and more particularly to wireless networks that include combination devices able to transmit according to two or more communication protocols.

BACKGROUND

Conventional short range wireless networks, such as Bluetooth (BT) networks, can enable networks (e.g., piconets) to be interconnected to one another by one or more devices to form a collection of interconnected networks (e.g., a scatternet). FIG. 12 is diagram of a conventional scatternet 1201. Scatternet 1201 can include three piconets 1203-0, 1203-1 and 1203-2, controlled by BT master devices B_M0, B_M1 and B_M2, respectively. Piconet 1203-0 can include slave devices B_S1 and B_S4. Piconet 1203-1 can include slave devices B_S2 and B_S3 and be connected to piconet 1203-0 by master device B_M0. Piconet 1203-2 can include slave devices B_S4, B_S5 and B_S6 and be connected to piconet 1203-0 by slave device B_S4.

Each master device (B_M0, B_S2, B_S2) can dictate communications of its piconet according to the BT protocol, which includes adaptive frequency hopping (AFH). Thus, piconets 1203-0, 1203-1, 1203-2 communicate according to AFH settings AFH0, AFH1 and AFH2, respectively. Because piconets (1203-0, 1203-1, 1203-2) of the scatternet 1201 are within close proximity of one another, transmissions from the various piconets can interfere with one another. This can degrade communications and/or require master devices to cycle through optimization procedures to arrive a best AFH setting for the environment.

It would be desirable to arrive at some way of improving transmissions of networks in proximity to each other, including but not limited to BT scatternets.

DETAILED DESCRIPTION

According to embodiments, systems can include combination devices that can communicate wirelessly according to two or more different protocols. A first combination device can determine configuration settings for a first protocol (e.g., optimal settings for the operating environment). The first combination device can then transmit such configuration settings according to a second protocol. A second combination device can receive the configuration settings according to the second protocol. The second combination device can then configure its communications according to the first protocol with the configuration settings.

In some embodiments, a first protocol can include frequency hopping, and configuration setting can be, or control, frequency hopping for communications according to the first protocol.

In some embodiments, first and second combination devices can be Bluetooth (BT)-WLAN combination devices that can communicate according to one or more BT standards and one or more IEEE 802.11 wireless standards.

In the various embodiments below, like items are referred to by the same reference characters, but with the leading digit(s) corresponding to the figure number.

FIGS. 1A to 1C are a sequence of block diagram showing a system 100 and operations according to embodiments. A system 100 can include a first combination device 102-0 and a second combination device 102-1. Each combination device 102-0/1 can include first communication circuits 106-0/1 and second communication circuits 104-0/1. First communication circuits 106-0/1 can communicate according to a first wireless protocol. Second communication circuits 106-0/1 can communicate according to a second wireless protocol.

First combination device 102-0 can serve as a master device to a number of slave devices 110-0 to 110-i and communicate with the slave devices (110-0 to 110-i) according to the first protocol as configured by configuration data 108-0. In a similar fashion, second combination device 102-1 can serve as a master device to a number of slave devices 110-j to 110-n and communicate with the slave devices (110-j to 110-n) according to the first protocol as configured by configuration data 108-1.

Referring to FIG. 1A, first communication circuits 106-0 within first combination device 102-0 can be configured according to configuration data CFGx 108-0, and thus can communicate with slave devices (110-0 to 110-i) in with first communication parameters, shown as 112-0. In some embodiments, communication parameters can include which frequencies and/or bands of frequencies are used, or how such frequencies and/or bands are selected. In some embodiments, communication parameters can include automatic frequency hopping parameters. Second communication circuits 106-1 within first combination device 102-1 can be configured according to different configuration data CFGy 108-1, and thus can communicate with slave devices (110-j to 110-n) with second communication parameters (different form the first communication parameters), shown as 112-1.

Referring to FIG. 1B, first combination device 102-0 can determine configuration data CFGz. In some embodiments, a first combination device 102-0 can make such a determination based on an operating environment of the first combination device 102-0. As but one example, such a determination can arrive at optimal settings for first communication circuit to operate in the environment. Configuration data CFGz may or may not correspond to the configuration data CFGx for the first communication circuits 106-0 of the first combination device 102-0.

Referring still to FIG. 1B, a first combination device 102-0 can transmit the configuration data CFGz to second combination device 102-1 over a wireless communication path 114 using its second communication circuits 104-0 operating according to the second protocol. A wireless communication path 114 can be a direct path (e.g., point-to-point) or can be an indirect path through one or more intermediate devices. In some embodiments, wireless communication path 114 can be an undirected transmission (e.g., non-addressed broadcast). In addition or alternatively, wireless communication path 114 can be a directed transmission (e.g., transmission addressed to the second combination device 102-1). A second combination device 102-1 can receive the configuration data CFGz through its to second communication circuits 104-1 operating according to the second protocol.

Referring to FIG. 1C, in response to the receipt of the configuration data CFGz, second combination device can reconfigure its first communication circuits 106-1 with the configuration data (i.e., CFGy replaced with CFGz). Consequently, first communication circuits 106-1 can communicate with slave devices (110-j to 110-n) with updated communication parameters, shown as 112-2 which may or may not be the same as 112-0.

In some embodiments, differences in configuration data 108-0/1/2 can result in differences in how frequency hopping is conducted. However, in alternate embodiments such a change in configuration data can change communication parameters other than those that establish frequency hopping. For example, configuration can result in selection or non-selection of particular frequencies, a selection of a smaller portion of a frequency bad (e.g., sub-band). One skilled in the art would recognize that embodiments can include the transmission of configuration data for implementing any other suitable difference in communication (e.g., changing from 112-1 to 112-2.

In some embodiments, one or both of combination devices 102-0/1 can be a single integrated circuit device. First and second communication circuits (104-0/106-0, 104-1/106-1) can be formed in a same integrated circuit substrate of their respective combination device 102-0/1.

FIG. 2 is a flow diagram showing a method 220 according to an embodiment. A method 220 can include a first portion 222 that can be executed by a first combination device, and a second portion 224 that can be executed by a second combination device. First and second devices can wirelessly communicate according to at least a first and second protocol.

A method 220 can optionally include a first combination device determining the presence of a second combination device 220-1. Such an action can include any option available under a second protocol, as but a few of many possible examples: a first combination device inquiring over the second protocol network (sending a beacon and receiving a response from the second combination device), a first device listening to the second protocol network (receiving a beacon from a second combination device), or a first device receiving information from another device on the second protocol device (e.g., access point device of the network).

A first combination device can determine an optimal configuration for a first protocol 220-2. Such an action can include a first combination device using configuration data of its own first communication circuits for operating according to the first protocol. Such an action can also include a first combination device executing an evaluation operation for the first protocol network. As but one example, a first combination device can cycle through available frequencies, bands, or channels, to determine which are busy, suffer from interference, etc. Such actions can also include a first combination device acquiring error information for the frequencies/bands/channels. A first combination device can develop configuration data from such a determination.

Once configuration data has been created, a first combination device can transmit the first protocol configuration data via the second protocol 220-3. As understood herein, such an action can include a broadcast transmission, an addressed transmission, or both. In some embodiments, such an action can include packetizing the first protocol configuration data.

A method 220 can include a second combination device receiving the first protocol configuration data via the second protocol 220-4. Such an action can include communication circuits depacketizing the configuration data. In some embodiments, such an action can include detecting a packet as being a special type that includes the configuration data.

A second combination device can then update its first protocol configuration data according to the received configuration data 220-5. Such an action can result in a second communication device being able to operate according to the first protocol in an optimal or near optimal fashion for the environment without necessarily having to execute an evaluation operation of its own.

Referring to FIG. 3A, a first combination device 302-0 can determine AFH configuration data (AFH1′) for a current operating environment. In some embodiments, configuration data AFH1′ can be determined to provide optimal performance for a given environment. Configuration data AFH1′ may or may not be configuration data utilized in the BT circuits 306-0 of the same combination device 302-0. Configuration data AFH1′ can be forwarded to WLAN circuit 304-0. WLAN circuit 304-0 can packetize the data and transmit it as a packet 328. Packet 328 can be a broadcast packet or a packet addressed to second combination device 302-1. Packet 328 can be transmitted to second combination device 302-1 directly, or the packet can be received by the second combination device 302-1 via one or more intermediate devices.

BT circuits 306-1 within second combination device 302-1 can operate with frequency hopping configured by configuration data AFH2. Configuration data AFH2 can be different than that of first combination device AFH1.

Referring to FIG. 3B, a second combination device 302-1 can receive packet 328 in WLAN circuits 304-1. WLAN circuits 304-1 can extract configuration data AFH1′ from the received packet and forward such configuration data to BT circuits 306-1. BT circuits 306-1 can receive transmitted configuration data AFH1′ and change operations to execute frequency hopping according to such data.
